This invention has to do withdouble: glass.

the area of such space but in thosedouble glassconstructions which have heretofore been proposed, the conductive character of the surrounding rails, even when the rails have been made in laterally separated sections, has inlarge measure offset the advantages derived by such insulation; dueprimarilyto the lack of insulation-- at the points of connection-between the sections.

The objectof the-presentinvention is toprovide an improved double-glass sash-inwhich the rails of the sash consist of two laterally separated frame members which are connected together in laterally spaced relation by the employment of novellyconstructed and arranged fastening means;

While the invention isespecially applicable to double glass sash, certain features of the same can alsobe utilized advantageously with sash-- having a single pane or any number of panes;

and with doors, panels, and the like, as well as sash.

Several different embodiments of the invention are presented herein by way of exemplification, but it will of course be understoodthat-the invention is susceptible of incorporation-in var.-

ious other structurally modified for-ms coming.

equally within the scope of the appended claims.

The embodiment of the invention which is shown in Figs. 1 to 43 inclusive, willfirstbe describedi Aswi-ll be observed in these views the frameof the sash consist's oi two generally rectangular sections or rim= members: t0 and M: which are spaced apart and extend continuouslyabout the edge of the sash. This frame con tainstwo panelsor panes I2 and 13- of glass and aglazing strip M 01" rubberhaving grooves I5 and I6 in which the edges of the panes. are tightly clamped. Theglazingstrip I4 is in turn tightly clamped between -two inwardly extending flanges FF and I 8-on the rim members In and H-.

The rim members=- l0 and I are provided. in addition to-thenanges -l l and 18', with outwardly extending flanges 1'9 and 20; laterally extending webs 21- and 2 2 and short outwardly extending flanges 23 and 25.: .atwthe confronting edges of the: webs. 21. and 2'2? The flanges 23 and 1 4 are spaced apart in generally parallel relation toteach other .adl'aoent the medium plane of the sash. The flanges: 19 andwm and the Webs 2,4; and 22 together form anoutwardly opening channel? for the recepti n he her ina e described. connectin m ans.

The connecting-means. n isis-9 a u al ty of E-shapedclamping blocks 2 5: which are pro? vided with. base portions inwardly extend: ing side projections 21 and 28,, an inwardly projecting: center projection 29; and inwardly extending grooves. so and: 3.4 between the side and center projections. lhese blocks are pref;- erably' formed from some" stron tough non conductive material, such as a: phenolic com.- pound, and are made-Sui liciently hard and rigid to withstand the clamping stresses to which subjected;

p tg block before ap 'The blocks 25 are located at intervals about the edge of the sash, within the contour of the frame, with the side projections 27 and 28 of the blocks arranged in clamped abutment with the oppositely facing seats 32 and 33 presented by the short outwardly extending flanges 23 and 24, and with the center projection 29 disposed between the flanges 23 and 24. The blocks are applied tothe sash after the panes I2 and I3 have been inserted in the grooves I5 and iii of the glazing strip l4 and after the glazing strip has been placed between the rim members l and H. The rim members l0 and II are forced together under pressure by any suitable means, until the glazing strip [4 has been compressed to the desired degree, whereupon the blocks 25 are inserted in their clamping-positions. The blocks will thereupon hold the rim members securely in position, in tightly clamped but properly spaced relation to each other. The ends of the side projections 21 and 2B are preferably beveled at 34 to facilitate their insertions. The blocks will be frictionally retained in place by the expansive action of the glazing strip 54. but if desired may be positively secured in position by means of small non-metallic and preferably resilient cleats 35 which are pivoted at 36 to the backs of the blocks andare movable into positions in which their ends engage within shallow grooves 37 in the edges of the flanges 23 and 24.

In the modified embodiment shown in Figs. to inclusive the spaced rim. members 38 and 39 of the frame are clamped together at intervals about the edge of the sash by blocks 46 which are similar to the'previously described blOCKS 25, but in this embodiment each of the rim members, instead of being of continuous onepiece construction, is jointed at 4! and 42, with the joints of one of the rim members staggered with respect to the oints in the other rim member. At the locations of these joints special clamping blocks 43 of greater length than the blocks 40 are employed The blocks 43 bridge the joints in each rim member, and the relatively short flange 44 of the rim member is cut away at each side of the joint at 45 and 46. The groove 41 in the block which receives the flange 44 terminates short of the ends of the block at 48 and 49, and the resulting solid portions 50 and 5| at the ends of the block extend into the cutout portions 45 and 45 of the flange 44 to lock endwise with the latterrand prevent the joint in the rim member from opening up.

In the modified embodiment shown in Figs. ll to 13 inclusive the clamping blocks 52 are U-shaped in form. In this embodiment the spacing portions of the blocks between the short flanges 53 and 54 of the rim members have been omitted. As in the other embodiments, the rim members are definitely spaced from each. other by engagement of the sides'of the blocks with the rim members at 55. The blocks 52 may be provided, if desired, with small indexing beads 56 which snap into shallow grooves 5'! in the confronting sides of the rim members.
